A square is the 2-dimensional hypercube. It has the schläfli symbol , as it is a four-sided polygon. Other names of square are called tetragon or tetrasquaron (Using Googleaarex's polytope naming system).
The square can be thought of as infinitely mine line segments stacked on each other in the y direction. As such, when viewed from a side, the sections are identical lines. It is composed of two pairs of parallel line segments.
When viewed from a vertex, the point will expand into a line of length before turning back to a point.
A square's vertices can be thought of as the combination of all ways you can arrange zero and one on a 2d grid.
